D5*15mm Terbium Gallium Garnet Single Crystal For Isolator

Introduction :

Terbium gallium garnet crystal (TGG) is a high-performance magneto-optical crystal in the visible and near-infrared spectrum. It is widely used in laser technology, optical communication, and optical information processing technology. It has the characteristics of high Feld constant, low light absorption coefficient, high laser damage threshold, and good optical performance. These good material properties make TGG crystal an ideal material for magneto-optical isolators.

In recent years, the growth of large-size and high-quality TGG crystals has always been a hot research topic in the field of crystal materials. With the unremitting efforts of the professional R&D team, Crystro has successfully grown TGG crystals with a diameter of 100mm in June 2020.
